Hi.A few days ago i started my r6 up,it idled for a few minutes and then shutoff on its on.I could not start it up again.So i took the spark plugs out and checked them and also checked if they fire.I thought it was the fuel pump.So i replaced the fuel pump and put new spark plugs.It started right up.I took it for a ride and i could not start to move only if i reved it pass 6000rpm.It lacks serious power and only struggles to rev up to 8000rpm and no further.Also if i open the throttle wide it a slows down.I suspect faulty coils,but i'm not sure.Any hints?Thanks

Could be. Could went bad on my '05 and it felt like I was riding a 3-cylinder. The engine was lacking power and it sounded like it was skipping a cylinder at idle. I was still able to ride it 50 miles to get home, but it was obvious something wasn't right.

Problem is i have planed a trip to Italy and i'm leaving on friday.I will make some calls tomorrow for 2 coils and see.Thanks

U riding the bike there?

 

[Spyrious]

Yes.

If u cant see any physical damage with a naked eye put a multi meter on them and ohm them, see if they read within spec. Also u can take a temp reading of the headers, the one that stands out from the other 3 will tell u the cylinder isn't firing. If u don't have a Pyro meter spare water on the header and watch bow quickly it boils/evaporates.

agreed. ^ .. need to stop throwing parts at it, and test the coils and fuel pressure before buying more stuff.

I will check with a multimeter today.The problem is that time is limited,as everything for the trip is booked.Thanks

Ok i checked coil resistance.Primary is 1.2Ω on all 4 coils and secondary is ~5kΩ also on all 4 coils.Primary seems out of spec as per manual while secondary is within specs.Does this mean all four are defective?

 

[MELK-MAN]

in my opinion, since all are measuring equal, they are fine. If one was out of whack from the others, i would suspect an issue.
While the coils are out, change the plugs (i think you did that already though). just some cheap ngk cr10ek is all you need (all i use in my race bikes, as do most racers i know), so don't bother with IR plugs. I

Yes.Spark plugs are new.I'm frustrated now.What else could it be?Thanks
